[BZ #3427]
2007-03-22 Jakub Jelinek <jakub@redhat.com> [BZ #3427] * sysdeps/x86_64/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions both in SW and MXCSR. * sysdeps/x86_64/fpu/feupdateenv.c: New file. * sysdeps/x86_64/fpu/feenablxcpt.c (feenableexcept): Remove dead code. * sysdeps/x86_64/fpu/fedisblxcpt.c (fedisableexcept): Likewise. * sysdeps/i386/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions in MXCSR if SSE is available. * sysdeps/i386/fpu/feupdateenv.c: Include unistd.h, dl-procinfo.h and ldsodefs.h. (__feupdateenv): Query exceptions also from MXCSR if SSE is available. Fix comment typo. * sysdeps/ia64/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions. Return 0 rather than 1. * sysdeps/ia64/fpu/feupdateenv.c (feupdateenv): Fix comment typo. Remove incorrect part of a comment. Fix argument to feraiseexcept. * math/test-fenv.c (feholdexcept_tests): New function. (main): Call it. 2007-01-05 Richard B. Kreckel <kreckel@ginac.de> [BZ #3427] * sysdeps/i386/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions in SW.
